IO::Socket::INET: Bad protocol 'tcp' at /tmp/script.pl line 7, <DATA> line 225.

You may receive this error if your system cannot convert the '''tcp''' protocol to its number using getprotobyname().

$ '''getent protocols tcp'''
$

In my case, this happened because after configuring a Solaris LDAP client using '''ldapclient'''. This command copies '''/etc/nsswitch.ldap''' over '''/etc/nsswitch.conf'''. The problematic line:
$ '''grep protocols /etc/nsswitch.conf'''
protocols: ldap [NOTFOUND=return] files

I changed the line to:
protocols: files ldap

and had no more problems.

$ '''getent protocols tcp'''
tcp 6 TCP
